I've made some good progress with my first attempt at a program, but have hit another road block. I'm taking standard output (as a string) froma console CMD window (results of dsquery piped to dsget) and have found small rectangles in the output. I tried using Regex to clean the little bastards but it seems they are related to the _ (underscore), which I need to keep (to return 2000/NT logins). Odd thing is - when I copy the caharcter and paste it into VS2K10 Express it acts like a carrige return?Going to try using /U or /A CMD switch next..
View 2 RepliesI have a very strange thing going on...I got a lot the CheckErrorStatus (Int32) error...and so I started to dig into my created functions. At the end I found what gave that error and so I added a new breakpoint on both computers where I want to run it (one is the developping computer, the other is the clients computer).
Developping computer : Windows 7, VS2008, .NET Framework 3.5SP1
Clients computer: Windows XP SP3, VS2008, .NET Framework 3.5SP1
the code of the function is a follows:

View 3 RepliesI a program that you can store stocks in,such information as name of the stock, price of the stock when you purchased it and so forth.This is stored in a file that is read and can be changed.My button that displays the information is giving me some problems as I have it setup and it will read my original file but when I add files its not going to display the new files.I need a way to make it output to my list box the new files as well as the old ones.right now my listbox outputs 5 lines, and each line has 5 records now the amount of records per line will not change but the number of lines I have will.I cannot pre write lines for something that has not happened, and I am stumped on how to fix this problem..
I am still learning and new to code so for me to write code that writes other code seems like some fantasy out of the terminator so I am sure there are much much simpler ways to do this than that.I am guessing using a loop and a variable in my array than the actual number something a long the lines of csvData(i)However I am just not seeing what syntax to use and how I would go about putting this together... Never came across anythign like this in the past.[code]any thoughts for ways to attack this problem and the type of syntax that would have to be used?

I would like to build inputs and outputs interface board (if you have schematics for the hardware or where I could purchase such thing) I need 9 inputs and 8 outputs, 24 volte DC for the inputs and I want to build a form in visual basic that utilizes the serial port so for example when I press Button1_Click it will make output number 1 goes high in the board and when input 9 goes high in the board label9 or Button3 will change color in the form.
So basically the IO interface and the form will only be used to energize relays and monitor these relays. I am not worrying at this moment about if this input is high make this output high but if this is possible in visual basic currently running Visual Studio 2008 Express.

I will be using .Net to communicate with a small unit that outputs data via a serial port. I have used an application that monitors the data between an application and this little box. What I see is functions such as IRP_MJ_CREATE, IRP_MJ_READ, etc. At first I thought I needed to build functions and I would send these via the serial port (a novice thought) now I see that the above functions are part of the Windows Driver Kit. So is it true that I call these functions in my code and then the underlying drivers communicate to the serial port and the approppriate data is seen at the serial port. So for .Net (VB) I need to find and use the appropriate functions and communicate to the serial port.

View 5 RepliesI'm trying to do is make a program to where when you click an option, a text outputs for each button clicked, the general design looks like this:
That's just a beginning, since the whole rest of the thing will be the same concept pretty much, and what I want to have it do is, like stated earlier, once the option is chosen, a text output, like this:
I know there is an alternative to solving that, but it will take me 10x more time, and that is, creating a new textbox, setting the visibility to False, and typing what I want outputted in that text box, then putting: RichTextBox1 = TextBox1.Text
I know that works, and gives me my output, but I just wanted to know if there was any other way but that.
I'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

I've tried a few alternative libs such as DirectShow.Net, DirectSound, BASS.Net, QuickTime and OpenTK.Some of them do what I need to do, but they are either too difficult to use and therefore impractical or they are missing some other essential features such as Events which are required to make the rest of the application work. Would anyone oppose to me posting this same thread on other forums?I will of course post a solution if one is found elsewhere without advertising external websites.

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?
